Recommendation points



A veranda in the country can replace a gazebo, a dining room, it is pleasant to arrange tea drinking on it. You can build a veranda with your own hands using the tips from our article. We will tell you how to calculate the material, assemble the frame, etc. This will help to avoid mistakes, save time and money.

Do-it-yourself veranda

The veranda is an unheated extension to the main building, which adjoins the house on one side, combining the functions of a porch and a place for rest. Unlike the terrace, it is built in the same style as the house and serves as a shelter from rain and sun.

The veranda can be:

  • with glazing (closed type);
  • without glazing (open type).

Selection of materials for construction

When choosing materials, one should proceed from the fact that the veranda is most often constructed according to the principle of frame technology. For racks, lower and upper strapping, a bar of 150×150 mm is used. It can also be used for floor logs. For the installation of the main floor trusses, a beam of a smaller section is needed – 80×100 mm. Intermediate rafters are made of 40×40 mm beams. Padding between uprights – 20mm edged boards or vinyl siding.

It is necessary to build a crate, which will require a smaller section bar (40×20 mm) or a metal profile. Stiffeners from the same timber are installed between the posts. The same timber is needed for the device of the roof sheathing. Ceiling lining is performed with 20 mm boards, moisture-resistant plywood or OSB boards. For the floor, use a grooved board with a thickness of at least 40 mm.

In order to know the exact amount of basic materials, before starting construction, it is necessary to make a sketch of the future veranda, which will indicate all dimensions.

The table shows the main materials. Some of them can be replaced, depending on personal preference, for example, for filling between the racks, you can use vinyl or metal siding, wooden lining or its kind – a blockhouse.

Foundation device for the veranda

For a light structure (which includes a veranda), the best solution would be to build a columnar foundation. This will significantly reduce the cost and speed up construction..

Special attention should be paid to the base elements located at the entrance: they must be stronger than others. This requirement is caused by the need to prevent the veranda from tilting away from the house, which often happens when the foundation pillars collapse. This can be avoided by the construction of additional supports..

The construction of a columnar foundation for the veranda is carried out in stages:

  1. The site is being prepared: trees and shrubs are cut down, stumps are uprooted.
  2. The marking of the installation sites for the supports of the columnar foundation is in progress.
  3. Pits are dug below the level of freezing of the soil (approximately 1.1–1.2 m), at the bottom of which a sand bed with a thickness of 150 mm is arranged. The sand must be moistened and tamped.
  4. Crushed stone is filled up with a layer of about 100 mm.
  5. Crushed stone is poured with a liquid cement-sand mortar, after which concreting is performed on top of it. The concrete layer should also be about 100 mm.
  6. Roofing material is laid on top of the concrete in two layers (for waterproofing). Brickwork is being carried out: brick columns of a square section (one and a half bricks) are being built. The height of the aboveground part should be such that the level of the veranda floor is slightly below the floor level of the main part of the house.

Note.It is recommended to lay the underground part of burnt bricks (they differ in the presence of characteristic black and brown inclusions): such bricks are better preserved in moist soil..

  1. All supports must be at the same level: this must be controlled with a water level.
  2. After the end of the laying, backfilling of the pits is performed. The soil needs to be compacted.
  3. Two layers of roofing material are also laid on top of the posts.

Attention! It is impossible to leave unfinished construction for the winter: due to the spring heaving of the soil, unloaded pillars can be unevenly displaced. It will be difficult to fix it.

Frame construction and wall construction

First, we mount the lower trim from a bar (all connections are made only above the foundation post). The timber in the corners is joined in half a tree and a spike is driven into a drilled hole with a diameter of 12 mm. For laying the lags, grooves are hollowed out every 50-60 cm.

The racks must be installed strictly vertically. They are fastened with brackets and special corner connectors. For ease of installation, the racks are temporarily fixed with jibs. The racks closest to the house should be made higher than the distant ones, so that the roof slope is at least 7 °: this is necessary to ensure good rainwater flow and snow melting.

The veranda frame will become stronger after installing the window sill beams between the posts. Distance from floor level – about 0.5 m (windows must be large).

The upper strapping is performed in the same way as the lower one. Grooves are hollowed out in it for the bars of the sheathing.

Diagonal elements (crosswise) are installed in the squares formed by the beams of the lower strapping, uprights and window sill beams, connecting them in half a tree – they will additionally strengthen the structure. The walls under the window are sheathed on the outside with boards or other suitable material (siding, panel boards, etc.). Between the inner and outer sheathing, a heat-insulating material is laid – mineral wool (if the veranda will not be used in the cold season, the insulation can be omitted).

Do-it-yourself veranda

Attention! The wood must be inspected and boards and beams with signs of decay and pests must be discarded. All wooden frame elements should be treated with an antiseptic, and after installation – apply a paint and varnish coating.

Roof and floor installation

On top of the mounted lathing we lay sheets of moisture-resistant plywood or OSB. We use bituminous shingles as a roofing material: under such a roof it will be more comfortable in the rain. You should also install a gutter with a slope of 3-5 ° towards the water outlet.

For the floor, you need well-dried, grooved grooved boards with a thickness of at least 40 mm. They are tightly driven together, leaving a compensation gap of 5-10 mm at the edges.

Note:for the floor to serve for a long time, the space between the foundation supports is not sewn up, or air vents are arranged (ventilation holes).

After that, a porch is attached to the veranda, doors are installed and glazing is performed. Windows can be with single glass: this is enough to protect from rain and wind. Window frames with double-glazed windows are necessary if the veranda is planned to be heated (in this case, all the cracks must be foamed and closed with platbands).

The last step is interior decoration. On the veranda, you can install a table for tea drinking, if space permits – you can install a dressing table and decorate with flowers and climbing plants, so that you can comfortably relax on the veranda during the summer heat or rain.
